Integrating the Final Windows 7 Updates (including Secure Boot/UEFI) into a Custom ISO – UpdatePack7R2 Guide
This article explains how Microsoft ended Windows 7 updates, details the Secure Boot/UEFI patch KB5017361 and its successors, and provides step‑by‑step instructions for using the UpdatePack7R2 collection to create a custom Windows 7 ISO that includes the final patches, drivers, and optional fixes.
Microsoft ended all updates for Windows 7 after the last patch on January 10, making any future patches unofficial third‑party releases.
In September 2022 Microsoft released KB5017361 adding Secure Boot + UEFI support, later updated to KB5022338/KB5022339, though the UEFI support was not explicitly documented.
The UpdatePack7R2 collection, created by a Russian developer, integrates the final important patch KB5022338 (or KB5022339) and can be applied to a Windows 7 SP1 ISO.
To generate a new ISO, drag the original Windows 7 SP1 ISO onto UpdatePack7R2‑23.1.11.exe and wait about an hour; the resulting ISO includes the integrated patches, IE11, and NVMe/USB 3.0 drivers.
When using the ISO, note that the boot.wim remains unchanged and may not support UEFI, so it is recommended to deploy install.wim in a WinPE environment; also inject up‑to‑date graphics drivers and replace acpi.sys for Intel 12th‑gen CPUs if needed (download link provided).
